INTRODUCTION

This Technical Reference Manual Slot provides information for the maintenance and service of the
Device Interfacing Solution, N-DISxxx. Please see also related Technical Reference Manual for
information related to system e.g. related documentation, conventions used, symbols on
equipment, safety precautions, system description, system installation, interfacing, functional
check and planned maintenance.

The purpose of the Device Interfacing Solution is to produce a data connection between an external
bedside device and an S/5 monitor.

The N-DISxxx is a new interfacing solution and works beside the previous interface solutions, B-INT
and M-INT that are still available.

Up to 10 devices can be connected simultaneously via device specific N-DISxxx modules.

1.3 Electrical specification

There is no isolation in DIS module. Interfaced device, DIS module and monitor must be situated in
the same patient environment (as defined in IEC 60601-1-1).

WARNING Connecting electrical equipment together, or using the same extension cord for

more than one device, may cause their leakage currents to exceed the limit
specified in relevant safety standards. Always make sure that the whole
combination complies with the international safety standard IEC 60601-1-1 for
medical electrical systems and with the requirements of local authorities.

1.4 Maximum power consumption

600 mW (75 mA @ 8 V)

1.5 Module communication

Bus communication speed is 500 kbps. RS422 implementation.

Device communication speed depends on the interfaced external device. RS232 implementation.

S/5 Device Interfacing Solution, N-DISxxx (rev. 00)

2 FUNCTIONAL DESCRIPTION

The S/5™ Device Interfacing Solution provides a seamless link between external patient care
devices and the Datex-Ohmeda S/5 monitoring system. You can interface simultaneously up to ten
external devices: monitors, ventilators, blood gas analyzers, etc.

The Device Interfacing Solution is designed for use with S/5 Anesthesia Monitor and Compact
Anesthesia Monitor, and S/5 Critical Care Monitor and Compact Critical Care Monitor. The Device
Interfacing Solution (DIS) is only compatible with the S/5 Anesthesia and S/5 Critical Care Monitor
when the monitor has B-UPI4(NET) and B-CPU4 boards installed. Also, DIS is only compatible with
the S/5 version (i.e. F-CM(REC)1 frame) of the Compact Anesthesia and Compact Critical Care
monitor. In addition, the S/5 Monitors must be equipped with DIS compatible main software. The
Device Interfacing Solution, N-DISxxx can not be used with AS/3 and CS/3 Compact Monitors.

WARNING The manufacturer guarantees a reliable functioning of the devices with tested

software versions only. Always refer to the Installation guide accompanying the
DIS module and verify the compatibility before use.

2.1 Main components

The implementation of Device Interfacing Solution can be divided into five parts:

• Device specific software

• Device specific module

• Device specific cable

• Bus cables

2.2 DIS module

A DIS module receives data from an external device, modifies the data to a suitable mode and
sends the data to the connected monitor. The main board contains the power supply with current
limiter, microcontroller, reset circuits, memory and serial communication buffers. The board
communicates with the Datex-Ohmeda monitor through the DIS bus.

A DIS module consists of:

• Power supply with current limiter and reset circuit parts

• Microcontroller H8, internal and external RAM, non volatile memory etc.

• Programming connection

• Device communication connection and RS232 driver

• Bus communication connection and RS422 driver

• LEDs, that indicate the status of the communication

• Device specific software
